    Creative geotechnical photography

    Inspired by her surroundings at RHS Rosemoor, where she was carrying out the ground investigation for a new educational facility, and with one eye on the Ruddlesden geotechnical site photograph of the year competition, Catherine Greed got creative with her site photography recently, framing the dynamic sampling rig within the last of the summer flowers.

    Pile Mat Design, Plymouth

    Geogrids were used as part of a pile mat design for a site in Plymouth. Calculations, which were undertaken in accordance with BRE 470: working Platforms for Tracked Plant, showed that a significant reduction in the platform thickness could be achieved if geogrid was incorporated into the platform construction, reducing the temporary works costs. Calculations were carried out for geogrids of varying tensile strength so that cost-benefit analyses could be carried out.

    Asbestos Testing Allays the Concerns of Locals

    As part of a larger contamination investigation and assessment for the residential development of a former power station, asbestos testing was undertaken. Anecdotally, asbestos containing materials (ACMs) arising from the decommissioning of the former power station had been encapsulated in a buried concrete chamber. Concerns were raised by locals and the local authority about how safe this was and whether the proposed development would endanger the general public, end users and construction workers. Intensive asbestos investigation and assessment, undertaken in accordance with the Control of Asbestos Regulations (CAR, 2012) and which included asbestos quantification testing, identified that the proposed remedial strategy to mitigate other contaminants at the site, which included raising the site levels and capping with inert soil, would also protect from the low levels of asbestos recorded in the soil., with no further measures required protect end users. The asbestos testing also enabled safe methods of working to be determined for construction workers.
